Assessment Guidance

Guidance for achieving higher grades

💡During practical assessments, narrate each step aloud to clearly demonstrate your understanding of why the action maintains asepsis.
💡Familiarize yourself with the specific SOPs of your workplace or training environment, as assessors will expect strict adherence.

Common Mistakes

Common errors to avoid in your coursework

Relying solely on gloves without proper handwashing, leading to potential cross-contamination when gloves are removed or torn.
Neglecting to allow sufficient contact time for disinfectants, assuming a quick spray is adequate to kill microorganisms.
Touching the inside of sterile containers or lids with fingers or non-sterile equipment, compromising the aseptic field.
